doc: Update removal of RCU-bh/sched update machinery

2018-08-30T17:59:48Z

The RCU-bh update API is now defined in terms of that of RCU-bh and RCU-sched, so this commit updates the documentation accordingly. In addition, although RCU-sched persists in !PREEMPT kernels, in the PREEMPT case its update API is now defined in terms of that of RCU-preempt, so this commit also updates the documentation accordingly. While in the area, this commit removes the documentation for the now-obsolete synchronize_rcu_mult() and clarifies the Tasks RCU documentation. Signed-off-by: Paul E. McKenney

kernel-per-CPU-kthreads.txt: standardize document format

2017-07-14T19:51:43Z

Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - Use title markups; - use "-" for bulletted lists; - Split Name/Purpose on two lines, in order to make visually easier to read (in text format), and to bold the title (on ReST output) - Add blank lines to split bulleted lists; - use sub-titles for the several kthread softirq types; - mark one literal var with asterisk as such, in order to avoid an error warning on Sphinx.

rcu: Eliminate NOCBs CPU-state Kconfig options

2017-06-09T01:52:43Z

The CONFIG_RCU_NOCB_CPU_ALL, CONFIG_RCU_NOCB_CPU_NONE, and CONFIG_RCU_NOCB_CPU_ZERO Kconfig options are used only in testing and are redundant with the rcu_nocbs= boot parameter. This commit therefore removes these three Kconfig options and adjusts the rcutorture scripts to use the boot parameter instead. Signed-off-by: Paul E. McKenney
